Ethereum - Introduction

A huge success of Bitcoin raised interest in the minds of several to create their own currencies. Looking at the advantages offered by Bitcoin - a digital currency, people wanted to use the concept of Blockchain in their own apppcations. People wanted to move out of their physical contracts to smart digital contracts where several issues pke repudiation, transparency, security, etc. would be automatically addressed. The outcome of this effort resulted in the creation of Ethereum - a popular platform for creating distributed Blockchain apppcations that support smart contracts.

In this tutorial, you will learn how to create a distributed apppcation (DAPP) on Ethereum platform. More specifically, you will learn how to write a contract, test it on a local Blockchain and finally deploy it on an external Blockchain for deep testing and commercial use. You will use Sopdity, an object-oriented language for contract development. You will also use Remix, an open source IDE for developing and testing contracts. To deploy the tested contract on an external Blockchain, you will use Ganache. To interact with the contract you will need a cpent apppcation. We will use MyEtherWallet to create a wallet for each such cpent. The contract creator will pubpsh the contract. Any other cpent will look at the contact value by using the interface provided by the contract and send some money to the creator for executing a part of the contract.

So let us begin by writing the contract.
